How to Protect a Screenplay, Script or Story Idea

You have a finished script, or a half-finished one, or just a premise you are terrified someone will steal the moment you pitch it. The fear is real and the advice online is a mess — “register with the WGA,” “mail it to yourself,” “you don’t own it until you copyright it.” Most of that is either wrong or only half true. Here is how protecting a screenplay or script actually works, in plain English.

What copyright actually protects in a script

Copyright protects original expression fixed in a tangible form. For a screenwriter, “fixed” happens the moment you type the script into a file, write it in a notebook, or otherwise commit it to a medium someone could read later. At that instant, you own the copyright. You do not have to publish it, register it, or add a copyright notice for the copyright to exist.

What copyright protects is the specific way you expressed your story — the actual dialogue, the scenes, the sequence of events, the particular characters as you developed them, the structure. What copyright does not protect is just as important:

• Ideas, concepts, and premises. “A heist crew pulls one last job” is an idea, and ideas are free for everyone. Two writers can independently write films from the same premise and both own their own scripts.
• Titles and short phrases. Copyright does not cover titles, names, slogans, or loglines. (Titles can occasionally get trademark protection in narrow circumstances, but that is a different system.)
• Facts and historical events. History belongs to everyone; your dramatization of it is yours.

This idea/expression line is the foundation of everything else. It is why you can protect a script you have written but cannot really “lock up” a concept you have only described. For the bigger picture of how copyright works, see how to copyright your work.

Copyright registration — why it matters and when to do it

If protection is automatic, why register at all? Because registration is what turns your copyright from a right on paper into a right you can actually enforce. Registering your script with the U.S. Copyright Office gives you three concrete advantages:

• You generally can’t sue without it. For works of U.S. origin, a copyright registration is a prerequisite to filing an infringement lawsuit in federal court. If someone lifts your script and you never registered, your first move is usually to register before you can even get into the courtroom.
• Statutory damages and attorney’s fees. Normally you would have to prove actual financial harm, which is hard and often small for an unproduced script. But if you registered on time, you can elect statutory damages — a court-set amount per work, no proof of dollar loss required — and ask the court to make the infringer pay your attorney’s fees. For a screenwriter, this is often the single most powerful tool you have, because it makes a lawsuit economically worth bringing.
• A presumption that your copyright is valid. A timely registration serves as evidence that you own a valid copyright, shifting the burden onto whoever wants to challenge you.

Now the rule worth memorizing — timing. Statutory damages and attorney’s fees are only available if your work was registered before the infringement began, or within three months of the work’s first publication. Miss that window and, even if you win, you may be stuck proving actual damages with no fee recovery. That is why writers who care about enforcement register early, not after a problem appears.

Registration is done online through the Copyright Office’s eCO system at copyright.gov. A screenplay is registered as a literary work; you complete the application, pay the filing fee, and upload a copy of the script as your deposit. Fees and processing times change, so confirm the current amounts on copyright.gov before you file.

WGA Registry vs. copyright registration

Here is where most screenwriters get tripped up. The Writers Guild of America runs a Registry (the WGAW Registry on the West Coast) where you can register a script. It is popular, cheap, and genuinely useful — but it is not a copyright registration, and it is not a substitute for one.

What the WGA Registry actually does is create a dated, sealed record of your material as it existed on a specific date. If a dispute later arises, a WGA employee can produce that deposited copy as evidence that you had that version on that date. It accepts not just scripts but treatments, synopses, outlines, and written ideas, among other materials.

What it does not do:

• It does not register your copyright or create any of the federal-law benefits above.
• It does not let you file an infringement lawsuit; only a Copyright Office registration satisfies that prerequisite.
• It does not unlock statutory damages or attorney’s fees.
• It does not carry the legal presumption of ownership that a copyright registration does.
• It expires. A WGA registration is valid for five years and must be renewed; a copyright lasts your lifetime plus 70 years.

So think of the WGA Registry as a timestamp and a deposit box — helpful corroborating evidence of when you wrote something — while a copyright registration is the actual legal instrument you enforce with. Many professionals do both: register the copyright for legal teeth, and register with the WGA for an extra dated record, especially during the messy revision-and-pitching phase. But if you only do one, do the copyright registration. For more on the registration mechanics, see how to copyright your work and the copyright topic hub.

Treatments, pitches, and protecting an idea

The hardest case is the one where you have an idea, a pitch, or a treatment — not a finished script — and you need to show it to a producer, executive, or contest before it is fully written. Copyright can only protect the expression you have actually fixed, so a one-paragraph logline gives you almost nothing to enforce. A detailed, written treatment is more protectable than a bare idea because it contains more original expression — but it still does not protect the underlying concept.

So how do people protect ideas they have to share? Two practical tools, both outside copyright:

• Confidentiality and contracts. A signed NDA, or even a clear written understanding before a pitch, can create enforceable obligations not to use or disclose what you share.
• Submission and implied-contract claims. When you pitch material under circumstances suggesting you expect to be paid if it is used, some states — California most famously — recognize an implied-in-fact contract or “idea submission” claim. These are state-law theories that operate where copyright does not reach. They are fact-intensive and far from guaranteed, but they are often the only avenue for an idea that was taken before it became a script.

We cover this in depth in our guide to idea theft and submission claims. The short version: protect ideas with contracts and good documentation, and protect scripts with copyright.

A protect-before-you-pitch plan

Put it together into a simple sequence you can follow before you send your work anywhere:

1. Finish a real draft and lock it. Copyright protects expression, so the more you have written down, the more you can protect. Save dated files as you go.
2. Register the copyright with the U.S. Copyright Office as a literary work, through eCO at copyright.gov, before you circulate it widely — and certainly within three months of any publication. This is the step that preserves statutory damages and attorney’s fees.
3. Optionally register with the WGA Registry for an extra dated record, especially as you revise. Treat it as evidence, not as your copyright.
4. Use NDAs and written terms when you must share a pitch, treatment, or early idea — that is where contract and submission-claim protection lives, not copyright.
5. Keep a clean paper trail. Save drafts, emails, submission dates, and who received what version. If a dispute ever arises, this record is what proves your timeline.
6. Re-register meaningful revisions. A substantially rewritten script is, in effect, new expression worth registering again.

The bottom line

You own your screenplay the moment you write it down — but ownership alone is weak. Register the copyright with the U.S. Copyright Office, and do it early, because timing controls your right to sue and to recover statutory damages and attorney’s fees. Treat the WGA Registry as dated evidence, not as a copyright, and remember that copyright protects your written expression, not your idea, premise, or title — protect those with contracts and confidentiality instead.
